ok, makes sense. i only use the name in the line below, to replace in the driver name pattern, i don't need the actual manager service name.

regarding the problem of default might not be named "default", i would inject two parameters then? the parameter name for an explicit manager name plus the parameter name for a fallback name to use if the default name does not exist? for the orm that would be `doctrine.orm.default_entity_manager` holding the *name* of the manager, not the *service name* right?
